Northern Dynasty has made clear it could apply for permits in the next three months. Apparently, they haven't gotten the message that we don't want an American natural treasure turned into an industrial wasteland.

No matter how you look at it, the Pebble Mine is a disaster waiting to happen. The EPA has confirmed that this gargantuan, open-pit copper-and gold-operation -- along with its estimated 10 billion tons of mining waste -- carries catastrophic risk for Bristol Bay, its legendary salmon runs, its pristine environment and its people.

Together, thanks to your activism, we've already done the near-impossible -- pushing two mining giants, Mitsubishi and Anglo American, to abandon this ruinous venture. And just last month, a third corporate backer, Rio Tinto, sent strong signals that it, too, is looking for the exit.

But Northern Dynasty Minerals remains in the grip of gold rush fever, and it's up to you and me to help break that dangerous spell.

It's imperative that we build on our momentum, seize this moment and put the last nails in the coffin of the Pebble Mine.
